In a recent interview, The Hills stars defended the 24-year-old's actions, saying:

Heidi: "She's had such unfair treatment all season long. They bait her, and she tries to make up with them and then they degrade her under their breath as a mom or a woman and whenever she stands up for herself, they call her crazy. They've had no respect for her from the beginning."

Spencer: "She was the only entertaining part of that show. She just owned it. It's awful how they called her 'disgusting on the inside,' and they just wouldn't stop. How would anyone react to that? As far as I'm concerned, with the way they've been attacking her, anything she does is self-defense."

We've been in there, we get it. But the bottom line is you should never resort to violence.

Farrah herself was spotted leaving the hospital in a wheelchair, so she may have also been injured during the fight — but what we do know for sure is that she's going to be far away from Thursday night's finale.
